National Forest Inventory (NFI)

Environmetrika supports scientifically defensible accuracy assessments of remotely sensed data with complex sample surveys for detailed indicators of forest condition and ecosystem health. The founder of Environmetrika has over 30-years of experience as a Project Leader and scientist with the Forest Inventory and Analysis (FIA) Program in the Research and Development Deputy Area of the USDA Forest Service, including Forest Health Monitoring (FHM) and the Northwest Forest Plan. 


Environmetrika is prepared to help scientists and technologists apply robust statistical estimators for complex sampling designs to their specifications.
